is Cape Diamond, and the rocks of the Cape and east of it 

 are much more massive than those to the west. They are 

 almost devoid of fossils. 



At the exposures of the Sillery, on the Levis side, just 

 northeast of the ravine at Hadlow, the lower part of the 

 cliff is seen to be made up of a bright red shale with green 

 spots and streaks, while the upper part of the bluff is 

 composed of green shale. In fragments of both red and 

 green shale on the talus at the foot of the cliff, specimens 

 of the only common Sillery fossil, Linarssonia pretiosa, 

 (Billings) may be found. 



From this place as far northeast as Point Levi red shale 

 and thin sandy beds form the cliff on the southeast. 



At Point Levi, it may be noticed that the red and green 

 shales extend as far as a small ravine close to the street 

 car switch, and that harder grey shales are then encountered. 

 Around the corner, behind the last house of the row to the 

 right are grey shales with occasional bands of red, but 

 beyond this point there is nothing but hard grey shale 

 and limestone. The first impression received is that the 

 Sillery lies above the grey shales, which belong to the Levis, 

 and that there is a gradation between the two indicated 

 by the alternation of red and grey beds. A closer study 

 of the cliffs, and the distribution of the beds on the flat 

 at the top of the cliff, shows that there is here in reality 

 a marked change along the strike, and that there must 

 be a fault separating the Levis from the Sillery. There is, 

 in fact, a small slip to be seen back of the easternmost 

 house, and there is evidence of disturbance in the little 

 ravine already referred to. 



From Point Levi to the foot of Davidson street, many 

 folds in the hard limestone are visible in the cliff along 

 Main street. 



On the eastern side of Davidson street some distance 

 above Main street and just below the bend in the road, 

 a cutting has revealed the arch of an overturned anticline. 

 The strata here are thin-bedded limestone and shale. 

 The limestone contains Dictyonema, Shumardia and other 

 fossils and is locally known as the Shumardia limestone. 

 The overturned condition of the strata is well shown here, 

 the dip being uniformly southeast at an angle of 50 except 

 for a short distance at the centre of the arch. The squeez- 

 ing out of certain beds, particularly a thick shale, is also 

 shown here.
